sapconf – A way to prepare a SLES system for SAP workload – Part 4
This is the forth article about sapconf and it will cover the deinstallation
NOTE: For further documentation check SAP note 1275776 and the man pages shipped with sapconf.
sapconf 4 → sapconf 5
Well nothing much to add here, besides that tuned is not covered anymore.
Really? You want to get rid of it? Well… If you really want:
sles12-sp3:~ # rpm -e sapconf Removed symlink /etc/systemd/system/multi-user.target.wants/sapconf.service.
Easy, wasn’t it?
But what is about the other packages that have been installed together with sapconf?
Well, they’re still there. tuned, sysstat and uuidd will not be removed.
sles12-sp3:~ # rpm -q tuned sysstat uuidd tuned-2.4.1-6.1.noarch sysstat-10.2.1-9.2.x86_64 uuidd-2.29.2-3.5.4.x86_64
If you remember, only uuidd.socket should still be active and enabled:
sles12-sp3:~ # systemctl status uuidd.socket ● uuidd.socket - UUID daemon activation socket Loaded: loaded (/usr/lib/systemd/system/uuidd.socket; enabled; vendor preset: enabled) Active: active (listening) since Fr 2018-05-11 15:02:42 CEST; 4min 19s ago
Tuned is not:
sles12-sp3:~ # systemctl status tuned sysstat ● tuned.service - Dynamic System Tuning Daemon Loaded: loaded (/usr/lib/systemd/system/tuned.service; disabled; vendor preset: disabled) Active: inactive (dead)
And sysstat is still active, but keeps disabled:
● sysstat.service - Write information about system start to sysstat log Loaded: loaded (/usr/lib/systemd/system/sysstat.service; disabled; vendor preset: disabled) Active: active (exited) since Fr 2018-05-11 15:02:42 CEST; 5min ago
So, if you want to use systat further, don’t forget to enable it!
Is there something else left, what is not that obvious?
Let me interrogate the man page:
sles12-sp3:~ # man 7 sapconf ... Note: If the package sapconf is removed from the system, the following settings will still remain: UserTasksMax setting in /etc/systemd/logind.conf.d/sap.conf Please remove the file manually, if it is not needed any longer. Note: A reboot is needed after the removal of the file to get the change take effect. Maximum number of open file descriptors in /etc/security/limits.conf Please remove the entries manually, if they are not needed any longer. A running sysstat service. Please stop the sysstat service manually, if it is not needed any longer. /etc/sysconfig/sapconf The central configuration file of sapconf is not removed during package removal. /etc/tuned/sap-* Private copies of tuned profiles in /etc/tuned are not removed during package removal. /var/log/sapconf.log The log file of sapconf will not be removed during package removal.
IMPORTANT: It’s always good to read the documentation! 😉
This again was a short article and you almost made it thru the series.
The fifth and final one will cover the leftovers.
